Data transmitting device uses no batteries, opts for environmental radio waves instead

We love stuff that works without batteries and electricity. Just recently, Renesas Electronics Corp developed a near-field wireless communication technology that’s capable of transmitting data without batteries. Using environmental radio waves to send data to Bluetooth– and wireless LAN (WiFi)-compatible devices, the system is sure to give rise to a bunch of products that could do with non-battery data transmissions.

A revolution in technology, soon, we could have small sensor devices that work without the need for electricity, helping us keep constant checks on their designated subjects by hooking on WiFi enabled devices!
